Spiral connecting portions having different angles, and the helical connecting portions are manually operated so that the center axis of the inclined spiral connecting portions is close to the center axis of the trunk edge or the center axis of the column. Is inserted into the trunk edge or the inside of the column.

According to the present invention, an inclined spiral shape with a simple configuration in which the cylindrical spiral connecting portion at the end of the wire rod in the fence panel attached to the trunk edge or the column is inclined with respect to the trunk edge axis direction or the column axis direction. The connecting portion is elastically deformed so as to correct the inclination of the spiral connecting portion along the axial direction of the trunk edge or the column, and the outer diameter of the spiral connecting portion is formed on the inner surface of the trunk edge or the column in the fence panel. It is possible to obtain an effect that can be engaged with each other so as to press the side, and can be connected in a state in which rattling between the spiral connecting portion and the trunk edge or the column on which the spiral connecting portion is mounted is reliably prevented. In addition, since the spiral connecting portion is disposed on the inner side of the trunk edge or the support column, there is no protrusion on the outer side of the trunk edge or the support column.
Further, the helical connection portion is inserted with an elastic force applied so that one of the radial pressing force and the other radial pressing force are suspended from the inner surface of the column or the trunk edge. And since a component force does not act on the wire connected to the spiral connecting portion, the form of the stitches of the fence panel is not changed.
In addition, when the spiral connecting portions that are adjacent to each other at intervals inserted into the support column or the trunk edge are spirals opposite to each other, they are adjacent to the trunk edge or the support column in the left-right direction (or up-down direction). One matching wire (for example, a vertical wire positioned on the left in the left-right direction) from the front side, and the other adjacent wire (for example, a vertical wire positioned on the right in the left-right direction) from the back side to the inside of the trunk edge or column In the case of mounting so as to be crimped to a wire rod (for example, a vertical wire rod), a horizontal wire rod (or a vertical wire rod) that is disposed at a position closest to the trunk edge (or support column) in the one and the other wire rods adjacent to each other. It is also easy to dispose the wires so that the wires are held from the front and back.
In addition, if the adjacent spiral connecting portions inserted inside the column or the trunk edge are spirals in the same direction, the fence panel can have a unified aesthetic appearance and can be easily manufactured. It becomes cheap and a mesh fence can be constructed at low cost.
In addition, if the fence panel is made of a crimped wire mesh in which the vertical wire and the horizontal wire are made of corrugated wire, and the corrugated concave and convex portions of each other are engaged, it can be transformed into a parallelogram, etc. Fence panels can be arranged according to the slope.
In addition, the vertical wire and the horizontal wire are made of corrugated wire, the straight wire portion is fitted to the corrugated concave portion of the vertical wire, and the straight wire portion is fitted to the concave portion of the horizontal wire. The fence panel is a stable fence panel because one side of the fence panel is smooth and there is no mesh movement.
In addition, since the support column is a fence panel corresponding to the inclined land, which is installed on the inclined ground, and the fence panel is deformed and attached to a parallelogram, It is possible to make a mesh fence that uses a fence panel that is compatible and excellent in aesthetics.
In addition, since the outer diameter side of the spiral connecting portion is crimped to the inner surface of the trunk edge or the support column, the outer side of the spiral connecting portion is engaged with the inner surface of the trunk edge or the support column so that the spiral connection portion is pressed. It is possible to prevent the connecting portion from shifting in the radial direction or the longitudinal direction of the trunk edge or the column.
In addition, when the spiral connecting portions having different inclination directions are arranged in a pair, the component force acting on the trunk edge or the column or the reaction force received by the vertical wire or horizontal wire cancels the component force received by the wire mesh. Therefore, since the vertical wire or horizontal wire does not move relative to the horizontal wire or vertical wire, there is no fear that the end of the wire will be displaced and the fence panel will be deformed, and the form of the installed fence panel will be stabilized. Can do.
In addition, the wire mesh is a wire mesh that can be deformed into parallelograms by knitting vertical and horizontal wires with corrugated irregularities, so that the wire mesh can be deformed into parallelograms in accordance with the road vertical gradient or boundary gradient. Can be easily accommodated.
In addition, when the cylindrical spiral connecting portion is a cylindrical spiral connecting portion, when the inclination of the portion is elastically deformed by manual operation, the worker uses it as a grip portion to It can be elastically deformed temporarily along the longitudinal direction and easily inserted into the torso or the inside of the column, and after the worker releases the spiral connection, the outside of the spiral connection The radial side can be engaged so as to easily press the inner side of the trunk edge or the support column.
In addition, the outer diameter side or inner diameter side of the spiral connecting portion is crimped to the inner side surface or the outer side surface of the trunk edge or the support column in the fence panel, and the wire end and the trunk edge or the support column on which the wire member is attached are rattled. Therefore, a stable mesh fence can be obtained without generating noise due to wind load or the like.
In addition, when the barrel edge is connected by a horizontal axis across a pair of spaced support columns, the column and the drum edge are relatively rotated before the column is fixed to the concrete foundation. Thus, it is possible to easily cope with a longitudinal gradient of a road or an adjacent land, and the degree of freedom in construction is high.
In addition, the spiral connection portion can be easily inserted into the trunk edge or the inside of the column only by setting the center axis of the inclined spiral connection portion close to the center axis of the trunk edge or the column. Therefore, the assembly of the fence panel and the trunk edge or the column can be easily assembled in a short time, so that the mesh fence can be easily constructed.
Further, the plurality of spiral coupling portions mounted on the trunk edge or the plurality of spiral coupling portions mounted on the support column each have a force acting on the trunk edge in the trunk edge axial direction. In order to suspend each other, or in order to suspend the forces acting on the pillars in the axial direction of the pillars, the spiral joints are different in inclination angle with respect to the trunk edge or the pillar, respectively. When the center axis of the inclined spiral connecting part is brought close to the center edge of the trunk edge or the column by manual operation, the spiral coupling part is attached to the trunk edge or the column when inserted inside the trunk edge or the column. Since the forces acting on the trunk edge or column are suspended by the multiple spiral connecting parts, the vertical or horizontal wire attached to the inner side of the trunk edge or column does not move relative to the trunk edge or column. And the mesh fence is deformed In addition, by manually operating the gripping portion of the spiral connection portion, the center axis line of the spiral connection portion is brought close to the center axis line of the trunk edge or the column, and the spiral connection unit is moved toward the trunk edge or the column. It can be easily mounted on the inside, and the mesh fence can be easily assembled and installed in a short time by work.

  Next, the present invention will be described in detail based on the illustrated embodiment.

  The fence panel 1 according to the embodiment of the present invention is configured by knitting a plurality of vertical wires 2 and horizontal wires 3 in a lattice shape. The vertical wire 2 and the horizontal wire 3 are bent into corrugations, and the corrugated portions are combined to form a crimp wire mesh. In addition, this invention is applicable also to fence panels other than a crimp metal-mesh.

  As shown in FIG. 3A, in the present invention, a spiral wound in a cylindrical shape such as a cylindrical shape at the ends of the vertical wire 2 and the horizontal wire 3 constituting the fence panel 1. A connecting portion 4 is provided.

  Each of the spiral connecting portions 4 of the vertical wire 2 and the horizontal wire 3 is provided so as to be connected to a linear portion 19 (see FIG. 2 or 11) near the ends of the vertical wire 2 and the horizontal wire 3, In the illustrated form, the spiral connecting portion 4 is formed by processing the tip of the linear portion 19 in a spiral manner. The linear portion 19 of each vertical wire 2 and the linear portion 19 of each horizontal wire 3 are provided at a position passing through the center or the vicinity of the center of the spiral connecting portion 4 in the diametrical direction. A straight portion 19 of the vertical wire 2 or the horizontal wire 3 can be arranged inside each slit 17 in the support column provided.

  In the illustrated embodiment, the spiral connecting portion 4 has the end portion of the wire continuously wound in a spiral manner, and the outer diameter is substantially the same in the longitudinal direction of the spiral connecting portion 4. In addition, the spiral connection portion 4 has an inner diameter that is substantially the same in the longitudinal direction of the spiral connection portion 4, and the spiral connection portion 4 is in relation to the main body side (fence panel side) of the wire rod. Thus, it is processed with an inclination angle α other than a right angle. Specifically, in order to arrange the spiral connecting portion 4 along the axial direction (longitudinal direction) of the trunk edge or the column, it is processed so as to be inclined with respect to the longitudinal direction of the trunk edge or the column.

  The inclination angle α is appropriately set depending on the wire diameter, the helical pitch, the number of turns of the spiral, and the like. When an operator manually changes the inclination angle α of the spiral connecting portion 4 and inserts the torso or the column, the inclination angle is more gentle than the steep inclination angle exceeding 45 ° (for example, 5 ° to 30 °). It is desirable that the angle is from 45 ° to 45 °.

  However, a steep inclination angle is more preferable than a gentle inclination angle because the crimping force that presses and engages the helical connecting portion 4 and the trunk edge or the strut increases. As described above, whether the inclination angle of the spiral connecting portion 4 is steep or gentle has advantages and disadvantages, and is appropriately set according to the design such as the wire diameter of the vertical wire or the horizontal wire and the number of turns of the spiral. However, it is desirable that the inclination angle α can be elastically changed by manual operation.

  As the spiral connection part 4, a spiral connection part that is separate from the main body part of the wire may be fixed by welding or the like, but the fence panel 1 main body part is configured as in the above embodiment. When the spiral connecting portion 4 is formed by bending continuously from each wire rod, an inexpensive spiral connecting portion 4 that is easy for an operator to change the inclination angle elastically by manual operation can be formed. It can be set as the wire which has the cheap helical connection part 4.

  The outer diameter dimension of the spiral connecting portion 4 is slightly more than the inner diameter dimension of the trunk edge 8 or the column 5 because the barrel edge 8 or the steel pipe column 5 arranged outside the spiral connecting portion 4 is arranged on the exterior. Small dimensions may be used. Further, in this case, in the longitudinal direction Y of the spiral connecting portion 4, the radially outer position on the proximal end side of the spiral connecting portion 4 and the radially outer position on the distal end side of the spiral connecting portion 4. The displacement difference A may be equal to or greater than the dimension difference obtained by subtracting the outer diameter dimension of the spiral connecting portion 4 from the inner diameter dimension of the trunk edge 8 or the column 5.

The middle part of the spiral spiral coupling part 4 may be a spiral coupling part that not only inclines linearly but also meanders somewhat. In the form in which the spiral spiral connecting portion 4 is inclined linearly as a whole, at least the proximal end side and the distal end side ring-like portion of the spiral connecting portion 4 have the slit 17 and the inner side of the trunk edge 8 or the column 5. If the spiral connecting portion 4 is a spiral connecting portion that meanders in the vertical direction, the front-rear direction, and further in the left-right direction, the body edge can be formed at two or three points in three dimensions. 8 or the post 5 can be crimped and engaged, and backlash can be further prevented.
The outer diameter of the spiral connection part 4 does not need to be the same diameter, and the diameter may change to some extent.

  In the case of the above-described embodiment, the outer diameter D of the spiral connecting portion 4 is a form in which the trunk edge 8 arranged outside the spiral connecting portion 4 is arranged to be extrapolated. Or what is necessary is just to be a dimension slightly smaller than the inscribed circle which contact | connects between the edge parts of the inner surface of the up-down direction (or left-right direction) in the inner side. Further, in this case, in the longitudinal direction of the spiral connecting portion 4, a radial outer position on the proximal end side of the spiral connecting portion 4 and a radially outer position on the distal end side of the spiral connecting portion 4. The displacement difference A is larger than the difference between the inner diameter of the trunk edge 8 or the support column 5 or the inscribed circle between the inner side end portions in the vertical direction on the inner side and the outer diameter dimension D of the spiral connecting portion 4. For example, the spring action can be exerted by elastic deformation, and the inner surface of the trunk edge 8 (or the support column 5 having the slit) can be pressed and locked.

  Further, since the trunk edge 8 or the support column 5 is extrapolated outside the spiral connection part 4 wound in the spiral shape, the pitch of the spiral of the spiral connection part 4 is set so that the trunk edge 8 or the support pillar 5 is outside. In the case of insertion, it is only necessary to extrapolate while being guided by the trunk edge 8 or the column 5 while the helical spiral connecting portion 4 is elastically deformed. If it is.

Next, a description will be given of a detachable connection structure with the trunk edge 8 or the column 5 on which the helical connection portion 4 of each of the vertical wire 2 and the horizontal wire 3 as described above is mounted.
The body edge 8 used in the present invention is a body edge having a slit 17 continuous in the longitudinal direction of the member, and the column 5 is a column 5 having a slit 17 continuous in the longitudinal direction of the member. .

  As shown in FIG. 1 and FIG. 4, a lid member that fixes a base end portion of a bracket 9 bent in an arc shape toward the body edge 8 is fixed to the upper end portion of the steel pipe support column 5 by fitting or the like. In addition, a lid member fixing a base end portion of a bracket 9 bent in an arc shape toward the column 5 is fixed to both ends of the steel pipe barrel edge 8 by fitting or the like, and the bracket 9 on the column 5 side is fixed. And the brackets 9 on the side of the trunk edge 8 are overlapped with each other, and a horizontal connecting shaft 10 (a connecting horizontal axis in a direction substantially perpendicular to the fence panel surface) inserted through these brackets 9 and 9. Accordingly, the support column 5 and the trunk edge 8 are connected to each other so as to be detachable, and the mesh fence 11 is connected so as to be slightly rotatable in the vertical direction.

  Therefore, in the state before fixing the column to the concrete foundation, the mesh fence that can easily cope with the longitudinal gradient of the road or adjacent land by rotating the column 5 and the trunk edge 8 relatively. Has been.

  When inserting the spiral connecting portion 4 into the trunk edge 8 or the column 5, the spiral connecting portion 4 is inclined as shown in FIG. 3A, and the column or column as shown in FIG. Insert into the barrel edge 8.

  In this case, the fence panel 1 can be manually operated by a worker using the inclined cylindrical connecting portion 4 at the end of each horizontal wire 3 constituting the fence panel 1 as a grip for manual operation. 1, the central axis of each spiral connecting part 4 inclined at the end of each horizontal wire 3 is extended from the upper part to the lower part, for example, from the upper part to the lower part. The base end side of the spiral connecting portion 4 and the vertical wire or the horizontal wire connected thereto are elastically deformed so as to be close to the central axis of the base, and the central axis of the spiral connecting portion 4 is brought close to the central axis of the column 5 In the state, it can be inserted into the support column 5. When inserting each spiral connection part 4 from the base end part of the support | pillar 5, it can be sequentially inserted and arranged from the base end part side of the support | pillar 5. As shown in FIG.

In addition, manual operation of the spiral connecting portion 4 at the end of each vertical wire 2 is sequentially performed from one end side in the left-right direction toward the other end side within the spiral connecting portion 4 at the upper end portion of each vertical wire 2. As described above, the base end side of the spiral connecting portion 4 is elastically deformed in the same manner as described above so that the center axis of each spiral connecting portion 4 approaches the center axis of the trunk edge 8, It is inserted and arranged on the end side of the trunk edge 8.
After that, after inserting the spiral connecting part 4 in an inclined manner, the outer peripheral side of each helical connecting part 4 is connected to the trunk edge by making the trunk edge 8 horizontal or inclined according to the installation ground, or by making the column 5 vertical. 8 (a) or the inner surface of the support column 5 is pressed and locked.
In this way, the outer peripheral side of each spiral connecting portion 4 is pressed and locked to the inner surface of the trunk edge 8 or the support column 5, and one unit of the form shown in FIG. 9 or deformed into a parallelogram is formed. A mesh fence 11 is configured. Note that one unit of the mesh fence 11 may be appropriately grounded.

  In the case of the body edge 8 in this form, the steel body edge 8 is provided with a slit 17 on the lower surface side and an inwardly supporting portion 18, and the inner end of each inwardly supporting portion 18 and the inner side of the body edge facing this The spiral coupling portion 4 having an outer diameter slightly smaller than the inscribed circle inscribed in the top surface T (see FIG. 11) is elastically deformed by the inner side of the trunk edge 8, The outer peripheral surface of the spiral connecting portion 4 such as the axial tip end and the axial base end side of the spiral connecting portion 4 is elastically pressure-bonded to the inner side surface of the trunk edge 8 or the inward support portion 18. It is the form which was made to stop.

  In addition, the cover material which fixed the bracket 9 to the horizontal hole provided in this at the both ends of the member longitudinal direction of the said trunk edge 8 is fixed by the horizontal axis, and the bracket 9 by the side of the trunk edge 8 and the support | pillar 5 side are fixed. A connecting shaft 10 made of a bolt or the like is inserted over the bracket 9 and is rotatably attached by a nut attached to the connecting shaft 10.

Since the fence panel 1 is a fence panel made of a crimp wire mesh in which the vertical wire 2 and the horizontal wire 3 are made of corrugated wire and meshed with each other's corrugated concave and convex portions, the corrugated concave and convex portions Since is not fixed, it can be transformed into a parallelogram as a whole.
In these cases, the inclination angle α is gradually changed to generate a crimping force.

  In addition, the bracket 9 at the end of the trunk edge 8 in the mesh fence 11 and the bracket 9 at the upper end of the support column 5 are connected by the connecting shaft 10 made of bolt / nut or pin joint as described above, A portal frame structure that can be deformed around the two connecting shafts 10 is formed.

  The fence panel 1 disposed in the portal frame includes a spiral connecting portion 4 at the upper end of the vertical wire 2 constituting the fence panel 1 and spirally connected to both left and right ends of the horizontal wire 3. A portion 4 is provided and these are knitted to constitute the fence panel 1.

  The concave portion 7 and the convex portion 6 of each vertical wire 2 arranged in parallel with an interval constituting the fence panel 1 are the convex portions 6 of the horizontal wire 3 arranged in parallel with an interval. And are engaged perpendicularly to the recess 7. The vertical wire 2 and the horizontal wire 3 are intertwined to form the fence panel 1, which is knitted so as not to deviate from each other. Such a fence panel 1 is connected to the trunk edge 8 and the column 5 so as to be crimped and locked.

  In addition, as shown in FIG. 19, it is desirable to provide the wire diameter of each vertical wire 2 and the horizontal wire 3 below the depth (h) of the corrugated recessed part 7. FIG. By configuring in this way, the vertical wire 2 and the horizontal wire 3 are accommodated and engaged in the recess 7 of the corrugated vertical wire 2 and the horizontal wire 3 corrugation, so that it is difficult to escape from the recess 7 and stable knitting. As you become more beautiful. Moreover, the vertical wire 2 and the horizontal wire 3 are appropriately used, for example, with a wire diameter of 1.6 mm to 2.6 or a wire diameter of 4 mm. For example, the wire diameter (d) and the wave diameter are based on a wire diameter of 4Φ mm. The depth (h) and pitch (p) of the concave portion of the mold may be provided at approximately 2: 4: 5, or may be provided at a ratio other than that. The vertical wire 2 and the horizontal wire 3 that are engaged with each other do not shift in the axial direction of the mating wire that is engaged with each other, and the depth (h) and the pitch are provided with a margin with respect to the wire diameter. Since (p) is set, the vertical wire 2 and the horizontal wire 3 are rotatable with respect to each other. That is, it can be smoothly deformed while maintaining the parallelogram of the mesh with the intersection of the vertical wire 2 and the horizontal wire 3 as a fulcrum.

  The single unit mesh fence 11 configured as in the above embodiment can be transformed from the state shown in FIG. 9 into a parallelogram state as shown in FIG. It is made available.

When the mesh fences 11 as described above are arranged in series (or refracted), as shown in FIG. 1 and FIG. A pair of band pieces 12 having recesses at both ends are arranged so as to face each other, and the band pieces 12 are fastened and fixed so as to approach each other by fastening bolts and nuts 13, and the upper ends of the columns 5 are connected to each other. Is done.
Each band piece 12 and the bolt / nut 13 constitute an upper fixing band 14.

  Moreover, the band piece 12 of the height as shown in FIG. 10 which heightened the height dimension similarly to the band piece 12 shown in FIG.1 and FIG.8 over the lower end part of the support | pillar 5 in the adjacent mesh fence 11 is arrange | positioned. In the same manner as described above, the lower ends of the columns 5 are connected and fixed by the lower fixing band 15 by a plurality of bolts and nuts 13 spaced in the vertical direction.

  Further, the lower fixing band 15 and the lower end portions of the respective columns 5 are embedded and fixed in the concrete foundation 16.

Next, the arrangement | positioning form of the helical connection part 4 of the edge part of the vertical wire 2 and the horizontal wire 3 is demonstrated with reference to FIGS.
5 to 7 and FIG. 17 or FIG. 18, the vertical wire 2 (or the horizontal wire 3) having the spiral connecting portion 4 inclined on one side, and the vertical having the spiral connecting portion 4 inclined on the other side. The wire 2 (or horizontal wire 3) is arranged so as to form a single or a plurality of symmetrical pairs, and the appearance of the fence is changed while suspending the force acting on the spiral connecting portion. It is shown.

  More specifically, as shown in FIG. 11, since the spiral connecting portion 4 is formed so as to be inclined with respect to the trunk edge 8 or the support column 5 in advance, a plurality of spaced helical connections are provided. In the state where only the distal end sides of the spiral connecting portions 4 are touched to each other (or the distal end side is touched more strongly than the proximal end side), a force for returning to the proximal end acts on the portions 4 (spiral against the trunk edge). Since the connecting part is displaced with respect to the longitudinal direction of the body edge such as the left and right direction, and the spiral connecting part is displaced with respect to the support column in the vertical direction), the spiral connection is arranged symmetrically in the inclination direction. In the parts 4, forces that try to return in opposite directions act on the trunk edge or the column.

  For this reason, the spiral connecting portion 4 is inserted with an elastic force so that the force pressing the strut 5 or the trunk edge 8 in one radial direction and the force pressing the other in the radial direction are suspended. ,desirable. In this case, for example, when the spiral connecting portion 4 is cylindrical and has a constant inclination angle α, the proximal end side and the distal end side are approximately one and the other with respect to the outer peripheral surface of the column 5 or the trunk edge 8. It is desirable because it comes to press almost evenly from the side.

  In addition, as shown in FIG. 11, the spiral connecting portions 4 of the vertical wires 2 (or horizontal wires 3) forming adjacent pairs at intervals are inclined with respect to each other, or one or more vertical wires are interposed therebetween. The slopes of the spiral connecting portions 4 that form a pair with a gap therebetween are symmetrically arranged so that the proximal end sides of the spiral connecting portions 4 are located farther from the distal end side of the spiral connecting portion 4. Alternatively, as shown in FIG. 12, the proximal end sides of the spiral connecting portion 4 are eccentrically arranged symmetrically in the radial direction of the spiral connecting portion 4, and the spiral connecting portion is arranged. The front ends of the portions 4 may be in a state of being eccentrically arranged symmetrically in the radial direction of the spiral connecting portion 4.

  For example, in Fig.5 (a), the vertical wire 2 which has the helical connection part 4 from which the inclination direction of the helical connection part 4 differs symmetrically on both sides of the one vertical wire 2 which is not provided with the helical connection part. In this manner, the component force received by the fence panel 1 is canceled by the component force acting on the trunk edge 8 (the same applies to the column) or the reaction force received by the vertical wire (or horizontal wire). Therefore, since the vertical wire or the horizontal wire does not shift and move, there is no fear that the fence panel 1 is deformed, and the form of the fence panel 1 can be stabilized.

  As the application mode, as shown in FIG. 5B, every other vertical wire 2 that does not have a helical connection portion, the left three wires having the helical connection portions 4 that are inclined in the same direction.
